A number of the heat dissipation devices can be installed on the outer surface of a building&#39;s exterior wall. Through the heat convection provided by the heat dissipation devices, the heat energy produced by sun is dissipated and the building&#39;s exterior wall is cooled down. The heat dissipation device can also prevent rain from permeating into the building.

TECHNICAL FIELD OF THE INVENTION

The present invention is generally related to heat dissipation devices,and more particular to a heat dissipation device installed on abuilding's exterior wall.

DESCRIPTION OF THE PRIOR ART

High rise buildings are common for accommodating the ever increasingurban population in the limited city space. These tall buildings arecrowded together and as such lead to poor ventilation. The heat absorbedby the buildings therefore is trapped and cannot be dissipated easily.

To overcome this problem, the present inventor provides a reasonablydesigned and effective solution as outlined in the following.

SUMMARY OF THE INVENTION

A major objective of the present invention is to provide a heatdissipation device for installing on the exterior wall of a building.The heat dissipation device is capable of conducting the heat energy orblocking out the heat energy from sun. The heat dissipation devicecontains a cuboid body, a number of support elements. The cuboid body ishollow with openings on a top side and a bottom side, respectively. Thesupport elements are positioned in the space inside the cuboid body,thereby partitioning the space into a number of heat dissipationchannels. The heat dissipation channels independently connect the topand bottom openings of the cuboid body. A number of the heat dissipationdevices can be installed on the outer surface of a building's exteriorwall. Through the heat convection provided by the heat dissipationdevices, the heat energy produced by sun is dissipated and thebuilding's exterior wall is cooled down. The temperature inside thebuilding is therefore prevented from rising too high.

Preferably, the cuboid body and the support elements are integrallyformed.

Preferably, the heat dissipation device is made of a flexible materialso that a number of heat dissipation devices can be pieced and rolledtogether.

Preferably, the cuboid body has one of a wave-like, a saw-tooth, and ahoneycomb-like cross-section.

Preferably, the heat dissipation device has a side coated with anattachment layer for attaching the heat dissipation device directly to abuilding's exterior wall.

The present invention has the following effects.

Firstly, the heat dissipation device can be directly and convenientlyinstalled on a building's exterior wall. Through heat conduction andconvection, the exterior wall is cooled down and the temperature insidethe building is reduced.

Secondly, there is no need to install additional and other heatdissipation apparatus for cooling down the building's exterior wall.

Thirdly, the heat dissipation device is able to protect a building'sexterior wall from rain. Some old building's rain leakage problem can beresolved as well.

The function and effect of the present invention are described asfollow. By having guiding ditches on the airflow guiding member andhaving the airflow guiding member detachably configured on the body, themanufacturing and assembly of the heat dissipation device is simplified.The higher cost due to the difficulty in working out guiding holes onextruded heat dissipation devices is as such avoided. Additionally, asthe width of the guiding ditch is gradually reduced from the receivingsection, through the regulating section, and to the guiding section, theairflow uniformly flows out of the body with an increased speed to forma planar air wall to confine pollutants in the air.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are exemplary embodiments only, and are notintended to limit the scope, applicability or configuration of theinvention in any way. Rather, the following description provides aconvenient illustration for implementing exemplary embodiments of theinvention. Various changes to the described embodiments may be made inthe function and arrangement of the elements described without departingfrom the scope of the invention as set forth in the appended claims.

As illustrated in FIGS. 1 and 2, a heat dissipation device 1 accordingto a first embodiment of the present invention contains a cuboid body10, a number of support elements 11, and a number of heat dissipationchannels 12. The cuboid body 10 is hollow with openings 101 on a topside and a bottom side, respectively. The support elements 11 arepositioned in the space inside the cuboid body 10, thereby partitioningthe space into the heat dissipation channels 12. In other words, theheat dissipation channels 12 are separated by the support elements 11,and independently connect the top and bottom openings 101 of the cuboidbody 10. In alternative embodiments, the cuboid body 10 can be shapedlike a thin plate, and the support elements 11 can be integrally formedwith the cuboid body 10.

A number of the heat dissipation devices 1 can be pieced laterallytogether to form a large planar structure, and the planar structure canbe installed on the outer surface of a building's exterior wall 20 (asshown in FIG. 6).

As shown in FIG. 2, through the heat convection provided by the heatdissipation devices 1, the building can be cooled down. Morespecifically, a number of heat dissipation devices 1 can be verticallystacked together through a connection mechanism or waterproof adhesiveso that their individual heat dissipation channels 12 are cascaded intoa number of heat dissipation channels that run along the outer surfaceof the exterior wall from the bottom to the top of the building. Whenthere is an imbalance of temperature distribution along the outersurface of the building's exterior wall, heat convection would occurwhere hat air would rise upward along with the heat energy of thevarious levels of the building, and cool air would be drawn into thecascaded heat dissipation channels 12, thereby achieving a reduction oftemperature along the building's exterior wall.

Preferably, a heat conduction layer (not shown) could be coated alongthe outer surface of the building's exterior wall before attaching theheat dissipation devices 1 to further effectively remove the heat energyof the building. The heat conduction layer can be made of a metallicmaterial or of a thermally conductive adhesive. Moreover, the heatdissipation devices 1 or the support elements 11 could be made of ahighly thermally conductive material such as a metallic material so thatthe exterior wall of the building can be cooled down through not onlyheat convection but also heat conduction. Additionally, as thebuilding's exterior wall is covered by the heat dissipation devices 1and therefore is protected from rain, the present invention provides awaterproof side effect.

As shown in FIGS. 3 to 5, various types of heat dissipation channels 12can be formed by appropriately configuring the support elements 11. Forexample, in FIG. 3, the support elements 11 are arranged to produce asaw-tooth cross-section in the cuboid body 10. In FIGS. 4 and 5, thesupport elements 11 are arranged to produce wave-like andtubular-channel cross-sections, respectively. Of course, it is alsopossible to achieve honeycomb-like cross-section. What are depicts areonly exemplary and are not intended to limit the present invention.

The installation of the heat dissipation devices 1 can also be modifiedas required. For example, each heat dissipation device 1 can have a sidecoated with an attachment layer made of waterproof silicone or thermallyconductive adhesive so as to attach the heat dissipation device 1directly to the exterior wall 20 of the building.

As shown in FIG. 6, the heat dissipation devices 1 can be prepared intoa roll of planar structure in advance. Together with the attachmentlayer, the heat dissipation devices 1 can be quickly attached to theexterior wall 20 of the building. In other words, the heat dissipationdevices 1 can be made of a flexible material so as to be rolled togetherfor convenient transportation, storage, and installation.

Exhaust fans can be further installed to the top ends of the heatdissipation channels 12 so as to draw the air inside the heatdissipation channels 12 for better heat dissipation efficiency.

While certain novel features of this invention have been shown anddescribed and are pointed out in the annexed claim, it is not intendedto be limited to the details above, since it will be understood thatvarious omissions, modifications, substitutions and changes in the formsand details of the device illustrated and in its operation can be madeby those skilled in the art without departing in any way from the spiritof the present invention.
